Since neither truth nor certitude is at hand
Do not waste your life in doubt for a fairyland
O let us not refuse the goblet of wine
For, sober or drunken, in ignorance we stand.– Umar Khayyam, Persian polymath and philosopher (1048-1131)

I like design to be semantically correct, syntactically consistent, and pragmatically understandable.
I like to be visually powerful, intellectually elegant, and above all timeless.– Massimo Vignelli, Italian Designer (1931-2014)
